Abstract (en)

[origin: WO2023274570A1] A coating, preferably a color coating, method for keratin fibers is described which includes three steps: activation, pretreatment and binding. The activation step includes one or both of a Praeparatur procedure and a Fundamenta procedure to produce modified fibers. The pretreatment step applies a pretreatment composition of at least a PTH alkoxysilane with PTH as a thiol, a protected thiol or a group complementarily reactive with thiol to the modified fibers to form pretreated fibers. The binding step applies a film forming composition to the pretreated fibers to form the color coating.
